"We had the most wonderful stay at hotel Grimsborgir! The rooms were spotless and very roomy. The hot-tub was also a great addition and lovely to be able to use it in the evening after a busy day of exploring. The staff were extremely friendly and the food (both the included breakfast and paid dinner) was amazing with lots of options. The location was excellent in a nice quiet part of Selfoss. We were also lucky enough to see the northern lights from our room!!"
